Operations Ventilation Modes
5.5 Ventilation Modes
NOTE: In all ventilation modes, when inspiration pressure reaches the high
alarm limit of Paw, the system switches to expiration immediately and
airway pressure is released.
NOTE: When the drive gas supply fails, mechanical ventilation cannot work
normally.
5.5.1 Monitored Parameters
NOTE: The monitored parameters are measured in the condition of ATPS
(ambient temperature and pressure saturated).
The A7 monitors the following ventilation parameters:
5.5.2 Ventilation Modes
The A7 provides the following ventilation modes:
5.5.3 Change Ventilation Mode
